Scaffolding device

ABSTRACT

A device to form a staging on a base such as the ground comprising a single upright support, a looplike member to embrace said upright support with arms on said member extending generally horizontally laterally from the upright support for engagement with a wall of a building to provide between the upright support and the building a rest for the formation of a platform.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1 I have shown the side10 ofa house with an uneven supporting surface 11 of ground adjacent tothe wall 10 of the house. Two uprights l2 and 14 are shown in spacedrelation which may be of any height, and the device which is the form ofthe invention is designated as 15 located upon these uprights andsupporting a plank 16 between the devices 15.

The device designated generally 15 comprises a member 20 of generallylooplike form, in this case being shown generally rectangular so as toembrace the generally rectangular upright support either 12 or 14. Arms21 and 22 are secured such as by welding 23 along opposite sides 24 and25 of the looplike member 20 and flare outwardly therefrom and areprovided with ends 26 which will engage the wall of the building such asshown in FIG. 1. In some cases a bar 27 (FIG. 5)'may extend betweenthese ends to provide a broader support and prevent the arms 21 fromspreading to a greater angular relation, The plane ofthe arms 21 and 22forms an obtuse angle 30 between the upright 12 and the plane of thearms 21, 22, thus giving some angularity to the upright support 12 withrelation to the wall of the house. The end of this support 12 may be ofany form, that being designated in this case as 31, so as to get a goodgrip on the ground 11, or it may be pointed to extend somewhat into theground. The loop 20 is angled in accordance with the angularity 30desired for the relationship between the upright support 12 and theplane of the arms as may be seen in the side view of FIG. 2, and therelationship between the embracing looplike member 20 is such that therewill be broad flat surfaces 33, 34 on the inside of the loop to engageand slide along the support 12. However, when the plank such as 16 isplaced upon the horizontal rest 21, 22 provided by the arms, there willbe a sufficient weight upon these arms so as to tend to swing the endsof the arms adjacent the building downwardly, causing the inner surfaceof the portion 33 of the loop to dig into the upright support 12 at 36which may be of wood or somethin of that nature, while the upper edge 37of the distant part 3 of the loop 20 W1 likewise dig into the support 12and thus provide a sort ofcramping action which will prevent the devicefrom sliding along the upright support or leg 12. However, in additionthere may be a setscrew 40 provided through the side 36 of the loop toassure that the loop will not slide along the member initiallyand untilthe weight on the arms has been located thereon, or it may be that thissecuring will provide a holding for the device in case the fit is notexactly correct. In some cases the arms now designated as 21' and 22 asshown in FIG. 6 may be of parallel relation, and a looplike memberdesignated 20' may be ofa size to embrace a ladder instead of a smallerleg such as designated 12 or 14 in the above figures.

In some cases, for more compact packaging for shipment, the device maybe made as in FIG. 7 where the loop 45 is cast with integral studs 46thereon over which tubular arms 47 may be telescoped in assembled formor detached from the studs for more compact packaging.

Ielaim:

1. A scaffolding device comprising a member of looplike shape and of asize to embrace an upright support, a pair of arms secured to saidmember and extending therefrom in spaced relation with their endportions shaped to engage an upright wall and provide a generallyhorizontal rest for the formation of a platform, an upright supportembraced by said loop member and of a size and shape to be slidable insaid member closely fitting the same and at an obtuse angle to saidarms, the diagonally opposite edges of said loop being sufficientlyangular and sharp to enter said upright support and bind thereon, and aplatform located on said arms urging the closely fitting loop memberinto binding relation with said upright support to prevent slidingtherealong.

2. A scaffolding device as in claim I wherein said upright support makesan obtuse angle within the under side of the plane of said arms.

3. A scaffolding device as in claim I wherein the arms have detachablesections.
